OIL-FEEDING DEViCE.

Specification of Letters Patent.

Patented J une 20, 1916.

Application filed October 1S 1915. Serial No. 56,730.

"Be it'known that 1, JAMES V. MonL nn, a citizen of the United States, and a resident of Oelwein, county of Fayette, and State of Iowa, have invented certain new useful Improvements in Oil-Feeding Devices, of which the following is a specification.

My invention relates to improvements in oil feeding devices especially designed for use in connection with steam engines, and has for its object the production of a device of this character which will be of durable and economical construction, and one which will be highly efficient in use. I

Otherobjects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood reference to the accompanying drawings forming a part of this specification; and in which, v

Figure 1 is a top plan. view of a device embodying the invention, the top plate of the housing or body thereof being removed to expose underlying parts, 2 isacentral vertical longitudinal section of the device, showing the slide valve and plunger thereof atoneterminal of movement, Fig. 3 is a jviewsimilar to Fig. 2, showingthe slide valve and plunger at the other terminalof their movement, Fig. 41 is a section taken on line o'a-emof Fig. 3, and Fig. 5 is a section taken on line y of 4.

The preferred form of construction, as illustrated in the drawings, comprises a rectangular housing or body ladapted, when the device is in use, to contain .the o l or lubricant which it is desired to feed to the engine in conjunction with which the device isemployed. Said; housing 1 is provided witha cover 2 which is hinged at one side as at 3 to said housing, the opposite side of said cover being releasably locked in closed position by means of screws 1 pivotally secured at their lowerends as at 5 to the housing 1, thumb nuts threaded upon the free ends of said screws being adapted for cooperation with bifurcated lugs 7 formed upon said cover. Ifdes1red the pivotal connection between said cover and housing may be dispensed with an'd in lieu thereof the screw .andrthumb nutconnection, employed at the opposite side of the cover, also usedat this side.

,sage leading to the chamber constituted by the channel 8 below plate 9. Leading from the under 'side of said chamber is an outlet passage 12.

' Mounted for reciprocation in channel 8, below'the plate 9, is a plunger 18 and a slide valve 1ft arranged end to end. Said plunger and slide valve are connected by means of a stein 15 projecting from said plunger which loosely engages in an opening 15 formed in the adjacent end of said slide valve. Threaded upon said stem is a nut 16 which is positioned in a-recess 17 formed for the reception thereof in said slide valve. Said recessis of a shape in cross section adapting the same to snugly receive the nut 16, as clearly shown in Fig. 4, whereby said nut is locked against relative rotary movement and hence adjustment of the parts, after once being set, is prevented except upon detachment of the plate 9 and removal of the l ng r and valve from the channel 8, it being clear that, when thus removed. said plunger and valve may be relatively rotated.

, ofthe oilthus admitted will bereturned or squirted upwardly through said slot until theright hand end of said plunger passes the remote edge of said slot, whereupon a certain quantity of oil will be imprisoned in the pocket A between the adjacent ends of 's 'aidplunger and valve. The oil thus impi-isonedwillbe carried to registration with thepassage 12. Cooperating with the slide valve 1 1 is a stop member 18 adapted to engage with said valve as the plunger 13 ap-' proaches its right hand terminal of movement and arrest the movement of said valve. so that upon continued movement of said plunger, the oil contained in the pocket A will be forced therefrom into the passage 12, as shown in Fig. 3. g

The passage 12 is controlled by a check valve 19 which serves to prevent backing up into the pocket A, said check valve being moved to open position by the pressure of the oil forced into the passage 12 by the plunger 13, as above mentioned. The pres sure upon the oil exerted by the plunger 13 is suflicient to overcome the influence of the spring cooperating with said check valve and also the steam pressure within the engine cylinder. Theupper side of check valve 19 is spaced slightly from the under side of slide valve 1 1 so as to insure an even distribution of pressure upon said check valve and thus prevent binding of the same when actuated. Upon movement of said check valve to open position, the oil flows around the same through passages 20 into pipe 21 which leads to the engine cylinder which it is desired to lubricate. The ports of passages 11 and 12 communicating with the channel. 8 are so spaced that at no time will the pocket A simultaneously reg ister with both, such an arrangement insuring against draining of the oil from housing 1 in the event of suction created in pipe 21, such as results as for instance when a' locomotive is drifting without the engine being in operation, it being known that in the latter case, vacuums are formed in the cylinders of the locomotive. Reciprocation of the plungerv 13, as described, is

effected by means of an enlargement or head 22 formed at one end of said plungerin which is provided a vertically elongated slot 23 with which cooperates an eccentric 24 carried by a shaft 25 rotatably mounted in housing 1. The bearings 26 at one end of shaft 25 are inclosed in a liquid tight 'cap 27, the opposite end of said shaft proj ecting eXteriorly-through a suitably packed bearing 28 and being equipped with a ratchet wheel 29. Loosely mounted upon the corresponding end of said shaft is a housing 30 in which is carried a pawl 31 adapted, upon oscillation of the member. 30, to engage with the teeth of ratchet wheel 29 and thus effect intermittent rotary movement of shaft 25 with the resultantreciprocation of plunger 13, as desired. The member 30 is formed. with a stem 32 in which is provided a plurality of spaced perforations 31 which afford means of connection by means of a link or arm with any sultable reciprocatlng portion of the engine whereby the member 30 may be oscillated. A plurality of perforations 33 is provided in order to afford adjustment of the throw of the stem 32 and hence regulation of the feed of oil to the engine.-

The device set forth is of course designed for use in connection with one cylinder, it being understood that where the steam engine'to be lubricated embodies more than one cylinder, a plurality of devices as described will be employed, one cooperating with each cylinder. Where more than one device is employed, the same may be driven separately or arranged abreast or united into one construction with very little change in the details described.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise, details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
